Allergy season is getting worse. Study shows that’s due to climate change
A new study points to climate change as the reason why you may be suffering seasonal allergies more often.
The study shared by research group Climate Central shows that the warming climate leads to “longer pollen seasons, worse allergies” for those sensitive to the airborne allergens.
“The first spring leaves and flowers are unfolding early in parts of the south including in Atlanta, Georgia and Charlotte, North Carolina,” the Climate Central website reads. “That’s bad news for people with seasonal allergies — about one-in-four adults and one-in-five children in the U.S.”
The Climate Central study examined temperature trends in nearly 200 cities across the United States from 1970 through 2024.
Their findings showed that “freeze-free” temperatures throughout the year have expanded over that time for 172 of those cities, leaving more time for plants to grow and release pollen.
The growing season expanded by 20 days a year on average, according to their findings.
